经典vue2结构 index.vue：

<template>
    <div>...</div>
</template>

<script>
? ? import method from "xxx.js"
? ? import component from "xxx.vue"
    export default {
      name: "ComponentName",
      props: {
        rowId: {
          type: Number
        }
      },
      components: {
        component1, component2 ..
      },
      data() {
        return {
          table: [],
          ...
        }
      },
      created() {
        ...
      },
      mounted() {
        ...
      },
      methods: {
        method1() {
        
        }
        ...
      }
    }
</script>

<style scoped>
  .style1 {
    width: 90px
  }
  ...
</style>

vue2的组件通讯方式有：

vue3记录

1、父组件向子组件传递参数（通过符号:），子组件通过defineProps接收：

//1、父组件中引入子组件并通过":"向子组件传值：
<Child info="我是父组件，给你钱" :money="money"></Child>

//2、子组件中使用"defineProps"接收：
<template>
  <div class="son">
       <h1>我是子组件:曹植</h1>
       <p>{{props.info}}</p>
       <p>{{props.money}}</p>
      <!--props可以省略前面的名字--->
       <p>{{info}}</p>
       <p>{{money}}</p>
       <button @click="updateProps">修改props数据</button>
  </div>
</template>

<script setup>
//需要使用到defineProps方法去接受父组件传递过来的数据
//defineProps是Vue3提供方法,不需要引入直接使用
let props = defineProps(['info','money']); //数组|对象写法都可以
//按钮点击的回调
const updateProps = ()=>{
  props.money+=10;  //props:只读的
  console.log(props)
}
</script>
